Steps to Calculate GCD of 645, 620, 792, 604 using LCM Formula

Given numbers are 645, 620, 792, 604

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(645, 620) = 79980

GCD(645, 620) = ( 645 x 620 ) / 79980

= 645 / 620

= 645


Step2:

LCM(5, 792) = 3960

GCD(5, 792) = ( 5 x 792 ) / 3960

= 5 / 792

= 5


Step3:

LCM(1, 604) = 604

GCD(1, 604) = ( 1 x 604 ) / 604

= 1 / 604

= 1


So, Greatest Common Divisor of 645, 620, 792, 604 is 1
